Cannot Find Firefox Files in Time Machine

I recently had to do a full erase and OS reload due to a boot-up issue. In order to reinstall my Firefox bookmarks, I went to Application Support in my Time Machine backup file, but there was not a Firefox folder there. I can access the folder on my computer, but not in TM.

Does Yosemite hide the file in TM like it does on the computer?

Any files that are normally hidden in OS X (user library folder) will remain hidden in Time Machine backups. You must unhide them to restore.
